Effect of additives on grinding of magnetite ore ...

1991-8-1  These investigations established that an addition of 200 g of CaO per metric ton of ore was the most effective in grinding quartz preferentially over magnetite at 75% solids concentration by weight. The limited rheological studies conducted suggest that the effect could either be due to dispersion or the structural modification of quartz.
